论文摘要
基于预先训练的语言模型（PRLMS）在源代码理解任务方面的巨大成功，当前的文献研究要么进一步改善PRLM的绩效（概括），或者它们针对对抗性攻击的鲁棒性。但是，他们必须在这两个方面之间的权衡方面妥协，而且它们都没有考虑以有效和实用的方式改善双方。为了填补这一空白，我们建议使用语义保护对抗代码嵌入（Space），以找到最坏的传播语义保护攻击，同时迫使模型在这些最坏情况下预测正确的标签。实验和分析表明，在提高PRLMS代码的性能的同时，空间可以保持强大的面对面攻击。
Based on the tremendous success of pre-trained language models (PrLMs) for source code comprehension tasks, current literature studies either ways to further improve the performance (generalization) of PrLMs, or their robustness against adversarial attacks. However, they have to compromise on the trade-off between the two aspects and none of them consider improving both sides in an effective and practical way. To fill this gap, we propose Semantic-Preserving Adversarial Code Embeddings (SPACE) to find the worst-case semantic-preserving attacks while forcing the model to predict the correct labels under these worst cases. Experiments and analysis demonstrate that SPACE can stay robust against state-of-the-art attacks while boosting the performance of PrLMs for code.
